SEATTLE – Work is underway to chop down trees along I-5 just as birds are settling into their nests. The tree cutting will make way for a new light rail line into Lynnwood, but the timing has riled some wildlife advocates.

Officials with Sound Transit said they have to cut the trees now to meet construction deadlines. However, that work is ramping up just birds head into the peak nesting season when they lay eggs and raise their young.
